Isaiah 56:6 means that people who are not born into Israel can still belong to the LORD. God welcomes foreigners who commit themselves to him, love his name, serve him, keep the Sabbath, and hold fast to his covenant. The verse was spoken by the prophet Isaiah, writing in God’s name, to a community that had recently returned from exile and was unsure who counted as part of God’s people.
Also the foreigners who join themselves to the LORD, to serve him, and to love the LORD’s name, to be his servants, everyone who keeps the Sabbath from profaning it, and holds fast my covenant…

What Isaiah 56:6 Means
The verse begins by naming the people it has in mind: foreigners who “join themselves to the LORD.” The picture is of someone attaching their life to God on purpose, the way a person might attach themselves to a household or a community. Their belonging is not based on ancestry or nationality but on a chosen relationship.
The verse then lists what that relationship looks like in practice. They serve the LORD, love his name, and become his servants. Keeping the Sabbath is named as a visible sign of this commitment, and holding fast to God’s covenant describes faithful loyalty over time. Each phrase describes a way of living, not a one-time decision.
It is also important to see what the verse does not claim. It does not say that these people earn God’s favor by a checklist of religious actions, and it does not promise that every outsider will automatically be welcomed in every situation. It describes how God’s grace opens his household to people who turn to him in faith and loyalty.
The Context of Isaiah 56:6
The book of Isaiah is a collection of prophecies traditionally attributed to the prophet Isaiah, though many scholars see it as the work of several hands across different periods. Chapters 56 through 66 are often grouped together and address the Jewish community after the exile in Babylon, when the temple had to be rebuilt and questions of identity and belonging were pressing.
Just before verse 6, the chapter speaks to foreigners and to eunuchs, two groups who were often excluded from full participation in temple worship under the old law. Verses 4 and 5 promise them a lasting name and a place within God’s house. Verse 6 then extends the same welcome to foreigners, and verse 7 describes God bringing them to his holy mountain and making them joyful in his house of prayer. Read in this setting, the verse is a declaration that God’s household is larger than the boundaries people had drawn around it.

A Short Prayer From Isaiah 56:6
Lord, thank you that your household is wider than any one of us could have imagined. Thank you for drawing near to people who once felt far away from you. Help me to join myself to you each day, to love your name above every other name, and to hold fast to the covenant you have made with me. Where I have quietly drawn lines around who belongs, show me where to open the door instead. Keep my heart steady in your welcome. Amen.
